Title: Floating fine-bubble aeration system
Inventor: REDMON DAVID T
IPC: C02F3/00
Filed: 2002-05-16
Granted: 2009-09-22
Abstract: A floating fine-bubble aeration system for dissolving a gas in a liquid in which the system is floated. A grid of uniformly spaced fine-bubble diffusers is used to establish large area of bubble-laden liquid, having a substantially uniform density. The uniform density prevents the formation of any upwardly directed currents within the interior portion of the area. Bubble residence time is maximized, due to the absence of the currents, thus increasing the efficiency of dissolving the gas in the liquid.
Patent CA-2448168-C (CA)
Inventor: JOERGENSEN OLE
IPC: E21B49/00
Filed: 2002-05-21
Granted: 2010-04-20
Abstract: The invention relates to a method of controlling the production of oil or gas from a formation (1) comprising that a first and a second drilled production well (105, 110) are formed next to each other that extend essentially horizontally; that, at the drilled production wells, a further drilled well (115) is formed that extends between the first and the second drilled production well (105, 110); that the production of oil or gas is initiated;  and that, while oil or gas is being produced, a liquid is conveyed to said further drilled well (115) and out into the formation (1) for a first period of time T1. The invention is characterised in that the pore pressure of the formation is influenced during the period T1 with the object of subsequently controlling the formation of fractures along a drilled well, typically across large distances in the reservoir. Such influence is accomplished partly by production in adjacent wells, partly by injection at low rate without fracturing in the well in which the fracture is to originate. Injection at low rate presupposes that an at least approximated determination is performed of the maximally allowable injection rate Imax for the period T1 in order to avoid fracturing ruptures in said further drilled well (115) when liquid is supplied by the injection rate I for the liquid supplied to the further drilled well being kept below said maximally allowable injection rate Imax for said first period of time T1 when the relation .sigma.'hole,min <=.sigma.'h has been complied with.

Abstract: A network security system includes a system data store (110) capable of storing a variety of data associated with a wireless computer network (180A, 180B) and communication transmitted thereon, a communication interface supporting communication over a communication channel and a system processor.  Data corresponding communications transmitted over the wireless communication network (180A, 180B) are received. One or more tests are applied to the received data to determine whether a particular communication represents a potential security violation. An alarm may be generated based upon the results of the applied test or tests. In some systems, configuration data associated with an access point on a wireless computer network potentially compromised by an intruder is received. Information contained within and/or derived from the received configuration data is stored. Communication with the intruder is continued by emulating the identification characteristics of the potentially compromised access point. A channel change request is transmitted to the potentially compromised access point and reroute communication between the potentially compromised access point and authorized stations such that communications may continue on a different channel.

Title: Methods and apparatus for reducing signal interference in a wireless receiver based on signal-to-interference ratio
Inventor: JIN XIN
IPC: H04Q7/32
Filed: 2005-06-29
Granted: 2012-01-10
Abstract: One illustrative method of reducing signal interference in a wireless receiver includes receiving a radio frequency (RF) signal; amplifying the received RF signal with a gain G; producing a baseband signal from the amplified RF signal; producing a signal-to-interference (S/I) ratio from the baseband signal; and adjusting the gain G based on the S/I ratio. Preferably, the gain G is varied over a time period to produce a plurality of S/I ratios, so that the gain G corresponding a maximum S/I ratio produced over the time period can be selected for optimal performance. With this technique, higher accuracy is provided as intermodulation distortion is accounted for in the S/I ratio. Advantageously, the S/I ratio calculations and the gain adjustments are performed digitally by one or more processors such as a digital signal processor (DSP).
